For her master’s thesis at the UCLA School of Nursing, Bates-Jensen developed a tool for measuring the status of chronic wounds, the Bates-Jensen Wound Assessment Tool. She went on to receive her doctoral degree from the school and to further her research in improving the quality of pressure ulcer and related care in nursing homes using technology, and methods of translating and maintaining effective research interventions into daily nursing home practice. Bates-Jensen is currently an associate professor at the school and in the David Geffen School of Medicine’s Division of Geriatrics. In addition to authoring numerous research papers on pressure ulcers, she is co-editor of the book Wound Care: A Collaborative Practice Manual for Health Care Professionals, now in its third edition, and has been a consultant for the U.S. Centers for Medicaid and Medicare Services on pressure ulcer related areas. She is currently evaluating a non-visual method of detecting early pressure ulcers using a device that measures skin and tissue water.
